WALTHAM, Mass. and BOULDER, Colo., Feb. 17, 2026 (GLOBE NEWSWIRE) -- Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today provided a business update and reported financial results for the fourth quarter and full year of 2025.

“Following three positive pivotal trials in 2025, we have entered 2026 with tremendous momentum and multiple value-creating regulatory catalysts underway,” said Andrew Robbins, Cogent’s President and Chief Executive Officer. “We have submitted our SUMMIT NDA for bezuclastinib in patients with NonAdvSM, initiated our PEAK NDA under the FDA’s RTOR program for bezuclastinib in patients with second-line GIST, and remain on track to submit our APEX NDA for bezuclastinib in patients with AdvSM in the first half of this year. These recent and upcoming milestones underscore the breadth of bezuclastinib’s best-in-class potential across KIT-mutant driven diseases. With a very strong balance sheet entering 2026, we will soon finish building our commercial organization and will be ready to launch bezuclastinib in the second half of 2026.”

Recent Company Highlights

• In February 2026, announced that six abstracts from the SUMMIT trial of bezuclastinib in patients with NonAdvanced Systemic Mastocytosis (NonAdvSM) have been accepted for presentation at the 2026 AAAAI annual meeting.
  
• In January 2026, announced that the U. S. Food and Drug Administration (FDA) agreed to accept the PEAK NDA for bezuclastinib in patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib under the Real-Time Oncology Review (RTOR) program. Shortly thereafter Cogent initiated the NDA submission to the FDA under this program. Based on the results from the PEAK trial, in January 2026 bezuclastinib was also granted Breakthrough Therapy Designation for this patient population.
  
• In December 2025, presented full data from the SUMMIT trial evaluating bezuclastinib in patients with NonAdvSM, at the American Society of Hematology (ASH) annual meeting, and submitted an NDA for bezuclastinib in NonAdvSM, supported by the SUMMIT dataset. Key findings from SUMMIT included:
  
  • Clear clinical benefit across all symptom domains, including significant improvements across 11 individual symptoms and the most severe symptom at baseline
    
  • Reduction in objective measures of disease, including serum tryptase, correlating with improvements in symptom severity, representing the first demonstration of this relationship in NonAdvSM patients
  • Forty-eight-week data showing continued deepening of symptomatic improvement over time
    
• In December 2025, announced topline results from the APEX trial evaluating bezuclastinib in patients with Advanced Systemic Mastocytosis (AdvSM), APEX is a registration-directed, global, open-label trial evaluating bezuclastinib in patients with AdvSM. Key findings included:
  
  • Rapid and deep clinical benefit, with an objective response rate (CR+CRh+PR+CI) of 57% per mIWG criteria and 80% per PPR criteria
    
  • A powerful effect on mast cell burden, with 89% of patients achieving a ≥50% reduction in bone marrow mast cells or clearance of aggregates

• In December 2025, announced initial preclinical results from the company’s novel, potent, selective JAK2 V617F inhibitor CGT1145 at the ASH annual meeting. These results showcased greater than 100-fold selectivity for JAK2 V617F mutations over JAK2 WT inhibition, positioning CGT1145 with a potential best-in-class profile.
  
• In November 2025, successfully completed concurrent public offerings of common stock and convertible senior notes for net proceeds of approximately $546.8 million.
  
• In November 2025, announced topline results from the Phase 3 PEAK trial of bezuclastinib in combination with sunitinib for patients with GIST who have received prior treatment with imatinib, becoming the first positive Phase 3 trial in second-line GIST patients in over 20 years. Highlights include:
  
  • 16.5 months median progression free survival (mPFS) for bezuclastinib plus sunitinib compared to 9.2 months mPFS for sunitinib monotherapy (HR=0.50, CI: 0.39-0.65; p<0.0001)
    
  • 46% Objective Response Rate (ORR) reported for bezuclastinib combination compared to 26% ORR for sunitinib monotherapy (p<0.0001)
    
  • The safety profile of the bezuclastinib combination was well tolerated with no unique risks observed with the combination when compared to the known safety profile of sunitinib
    
• In October 2025, shared progress on Cogent’s internally developed KRAS(ON/OFF) inhibitor CGT1263 in a poster at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. Updated results demonstrated clear selectivity over HRAS and NRAS, with picomolar (pM) activity across a broad panel of KRAS mutant cell lines. In addition, the poster also characterized CGT1815 (the prodrug of CGT1263), which is designed to optimize human pharmacokinetic performance, supported by pharmacokinetics data from both CGT1815 and CGT1263 across multiple species. Finally, the poster highlighted outcompete data in KRAS^G12D and KRAS^G12V tumor growth inhibition studies when compared to other KRAS exemplars including RMC-6236.

Fourth Quarter and Full Year 2025 Financial Results

Cash and Cash Equivalents: As of December 31, 2025, Cogent had cash, cash equivalents and marketable securities of $900.8 million. Fourth quarter cash usage was driven largely by non-recurring items, including the repayment of $54.8 million of long-term debt and approximately $38.5 million of one-time, performance-based equity compensation.

R&D Expenses: Research and development expenses were $75.6 million for the fourth quarter of 2025 and $269.8 million for the year ended December 31, 2025, as compared to $62.0 million for the fourth quarter of 2024 and $232.7 million for the year ended December 31, 2024. The change was driven by the continued development of bezuclastinib across three pivotal trials, including costs associated with the completed and planned NDA filings, as well as the continued progression of our early stage, preclinical and discovery programs. R&D expenses include non-cash stock compensation expense of $7.5 million for the fourth quarter of 2025 and $23.1 million for the year ended December 31, 2025, as compared to $5.0 million for the fourth quarter of 2024 and $19.0 million for the year ended December 31, 2024.

G&A Expenses: General and administrative expenses were $23.9 million for the fourth quarter of 2025 and $63.6 million for the year ended December 31, 2025, as compared to $11.7 million for the fourth quarter of 2024 and $43.3 million for the year ended December 31, 2024. The increase was primarily due to the growth of the organization and activities related to the anticipated commercial launch of bezuclastinib. G&A expenses include non-cash stock compensation expense of $8.3 million for the fourth quarter of 2025 and $23.0 million for the year ended December 31, 2025, as compared to $5.0 million for the fourth quarter of 2024 and $20.8 million for the year ended December 31, 2024.

Net Loss: Net loss was $102.5 million for the fourth quarter of 2025 and $328.9 million for the year ended December 31, 2025, as compared to a net loss of $67.9 million for the fourth quarter of 2024 and $255.9 million for the year ended December 31, 2024.

About Cogent Biosciences, Inc.
Cogent Biosciences is a biotechnology company focused on developing precision therapies for genetically defined diseases. The most advanced clinical program, bezuclastinib, is a selective tyrosine kinase inhibitor that is designed to potently inhibit the KIT D816V mutation as well as other mutations in KIT exon 17. KIT D816V is responsible for driving Systemic Mastocytosis, a serious disease caused by unchecked proliferation of mast cells. Exon 17 mutations are also found in patients with advanced Gastrointestinal Stromal Tumors (GIST), a type of cancer with strong dependence on oncogenic KIT signaling. The company also has an ongoing Phase 1 study of its novel internally discovered FGFR2 inhibitor. In addition, the Cogent Research Team is developing a portfolio of novel targeted therapies to help patients fighting serious, genetically driven diseases targeting mutations in ErbB2, PI3Kα, KRAS and JAK2. Cogent Biosciences is based in Waltham, MA and Boulder, CO. Visit our website for more information at www.cogentbio.com.
